This invention relates to filling devices for small containers, particularly jarsor pitchers for cream, syrup and the like, and has for its main object to provide such a device which will be 5 efficient and practically automatic in its operation.

Another objectof this invention is to provide a device of the character mentioned, which will be adapted to ll a -great many of such small l containers, pitchers, jars and the like simultaneously removing the row when lled and replacing it by a new row of such containers easily and quickly.

Still a further object of my invention is to l provide a i'illing device for a plurality of such small containers which will be safe against waste of spilling of the material t0 be filled. which will be secured against over or under lling or the containers or any of them, and which will also 20 seal the containers when lled to the desired y 30 removal and so on will be done in succession in a semi-automatic manner by the .device itself.

Still further Aobjects of thisinvention will be apparent as the specification of the same proceeds. 35 In the drawings forming a part of this specication and accompanying the same:

Fig. 1 is a plan view of my device, the upper party of the front portion of `the same having been removed;

Two upper side plates I I3"and Mare secured to 5 the table plate I0, forming a U-shaped upwardly open structure in which is housed most' of the operation parts of my device. A stationary cover plate I5 is secured over thevtable plate Il), spaced apart therefrom, leaving sufficient room fora sliding plate I6 between' the two. A generally rectangularly shaped crossbar I1 is arranged over the table plate I0 in the front part thereof, resting on two coiled springs I8 and I9 which have the tendency to push said cross bar I'I in l5 an upward direction, said bar being slidably arranged on pins and 2I.

A plurality of iilling funnels 22 are secured, preferably in an evenly spaced apart manner in the cross bar I1, each having an upwardly widen- 20 ing upper funnel 23, a central tube portion 24 l and a lower downwardly widening funnel 25 with a cylindrical termination v'26. A hole 21 is provided in the table plate I0 under each cylinder 26, said cylinder being adapted to snugly but 25 slidably pass through the respective hole 21, while the upper cover plate I 5 is shorter than the table plate IIJ so as to leave `the hole 21 free and uncovered.

A rectangular hollowbody or filling containerY proper 28 is arranged across mydevice secured into the upper side plates I3 and Il, being axi- .ally aligned with Vthe filling funnels22 and having a small lling hole or aperture 29 in its bottom corresponding to the center line 'of each 35 filling funnel 22.' A general reservoir `30 is arranged over said fillingcontainer 28, communicating therewith through thevpipe connection QSI. A longitudinal bar `or plate 3 2`is arranged within the closed lling container prcper 28, being upf 40 wardly and downwardly slidable therein zand having a small downward closing "pin` or" needle 33 for each opening 29, and an upward-center ,rubber ldisk 3.4 for closingfofopeningfthe `com-- A longitudinal frame member or plate 38 is secured to the lower ends of the downward bars 31, said plate 38 slidably engaging the inner wall 39 of the rectangular filling container proper 28. At two places, the sliding plate 38 is downwardly extended and inwardly projecting to form two fingers or arms 40, and a coiled spring 4| is placed between each arm or finger 40 and the bottom 42 of the filling container 28.

Between two lugs 43 and 44, secured on the cover plate I5 in the center line thereof, is a plate lever generally indicated by the numeral 45, rockable on a p ivot 46 and carrying the handle 41 by which it may be manipulated. A slot 48 is provided in the cover plate I5, permitting the outer circumferential portion of the plate lever to'enter and slidably move in said slot, and the sliding plate I6, under said cover plate I5, has a plurality of apertures 49 ar- .ranged in alignment with said slot 48, and teeth 50 arranged on a portion of the circumference of the rockable plate lever 45 may engage said apertures and move said plate I6 in either direction between the plates I0 and I5, as will be explained hereinafter. (Stroke and directions indicated at |8a, Fig. 6.)

Also rockable between the lugs 43 and 44, as

around the pivot 5I, is the lever 52, having the'- inner branch 53 adapted to be engaged with the various cam surfaces on the plate lever 45, and the outer branch 54, reaching underneath the sliding plate 38, and the filling container 28, and over the cross bar I1. Two supporting and guide rails 55 and 56 (Figs. 2 and 3) are secured to the inner sides of the lower or leg plates |I and I2, and a plate 51 is slidably resting on them between said two leg plates. Longitudinal walls 58, and transverse walls 59 are built on said plate 51, providing a receiving frame with compartments 60 for receiving rows of small containers or pitchers 6|, as will be understood. Outside of said compartments on the two longitudinal marginal edges of the plate 51, equidistantly spaced, teeth 62 are provided in the surface of the plate and another row of equidistantly placed slots 63 are cut into the respective edges of the plate 51.

On the inner side of each of the leg plates II and I2 is arranged a link mechanism, generally indicated by thenumeral 64, consisting of a lever 65 rockable on the pivot 66, the lower-end 61 of which is pvotally connected to a propelling finger or arm 68, while the upper end 69 thereof is pvotally connected to a link memsis' ber 18, the forward end 1| of which is again pivoted on a small plate 12, depending from the respective side of the 4sliding center plate I6, the main or table plate I 0 having a slot provided therein (not shown) adjacent to each leg plate I| and I2 to permit a backward and forward moving of the depending plate 12.

The use and operation of my device is as follows:

The compartments 60 on the sliding plate 51 will be filled with the pitchers or containers 6| and then placed over the rails 55 and 56 and pushed forwardly in the device until the rst row of said containers, generally indicated by the numeral 14, is set in alignment with the 38 will carry downwardly the two upward bars 21, the cross bars 36 and the pins or rods 35,

and the longitudinal bar 32 in the container 28 will be placed downwardly closing the exit or filling openings 29, in its bottom, through the closure pins 33 and opening the connection 3| to the reservoir 30. This is the normal state of said parts of my device, so that, normally, the filling container 28 is open to the reservoir 3|] and will be filled with the contents 15 of said reservoir, like cream, syrup, etc., while the exit openings 29 of the filling container 28 are normally closed preventing the escape of any material therefrom.

When it is desired to fill the said first row 14 of containers in my device, the handle 41 will be turned upwardly, as shown by the arrow 11, to its uppermost positions, as indicated in an imaginary fragmentary manner at 41a by the dot and dash lines in Fig. 3, in which position the upper cam portion 18 of the rocking plate lever 45 will engage the left-hand end 53 of the rocking lever 52 and will press it downwardly, as indicated by the arrow 19, and causing the branch 54 of said lever to move upwardly, as indicated by the arrow 80, engaging and moving the plate 38 in an upward direction. Such a movement of the plate 38 will carry all the devices secured to said plate in an upward direction in a similar manner as has been described in connection with the movement of said plate 38 in a downward direction, ultimately moving the closure pins, 33 upwardly out of the filling openings 29 and, at the same time, closing the exit 3| from the reservoir by the disk valve 34.

The contents of the filling container 28 is now permitted to flow out through the openings 29 through the intermediate filling funnels and tubes 22 into the containers 6|, and said container 28 is designed in such a way that its contents will be exactly sufiicient to fill each container 6| to the desired degree.

After the container 28 has been emptied of all the liquid and all the pitchers 6I have been filled, the operating handle 41 of my device will -be `turned in a reverse direction, backwardly or downwardly, as indicated by the arrowl 8|, and its cam 18 will release the branch 53 of the rocking lever 52, whereupon the branch 54 of said rocking lever will at once be moved downwardly in the reverse direction to arrow 80, permitting the springs 4| to act to move the plate 38 and its associate parts downwardly, returning the longitudinal bar 32 in the container 28 into its said normal position, sealing the ein't openings 29 by the pins 33, and permitting the reservoir 30 to refill said container 28, as will be understood.

On the further rotation of the handle 41 and plate lever 45 in the direction of the arrows 8|, the teeth 50 will engage the apertures 49 and will move the plate I6 in a forward direction, indicated by the arrow 82, in Fig. 5. An appropriate sealing disk 83 has been placed into each semicircular front reces's 84 of the plate I6 over the table plate I0 by a device and in a manner to be described presently, and on the forward movement of the plate I6 in the direction of arrow 82, each disk 83 will be dropped over a respective container 6| through the respective opening 21 in the plate I0, as will be understood. A further movement of the plate lever 45 in the direction of arrow 8|, that is, a further pressing of the handle 41 in a rearward direction, will move the teeth 50 out of engagement with the plate I6 and will place a second cam portion 85 of the plate lever 45 into engagement with the end 53 of the rock- 75 2,167,624 ing lever 52,'as indicated in Fig. 3, and upon the" further pressing ofthe handle 41 and rocking of the platelever 45y inthe direction of `arrow 8I, said cam 85 will lift orraise the leverend 58 upwardly, opposite to the direction of .arrow 19, and' will move the lever end 5l!k downwardly, opposite i tothe arrow- 80, said lever end 54 now engaging the crossbar I1 and pressing it downwardly,`

Aagainst the action of thesprings I8 andy I9, the lower cylindrical ends of the filling funnels 22 entering the upper openings of the pitchers or containers 6I` and sealingly pressing the respective disks 83 thereinto. In this manner, the first row of the containers 6I has been filled and sealed, and my device is ready to fill and seal the second row thereof. For this operation, lever 41 will again be pushed into its uppermost position 41a 1 and the operations described hereinbefore repeated.

It will be noted that upon the upward movement of the handle 41 in the direction 11 from the position indicated in Fig. 3, after sealing the rst row 14 of the lled containers, teeth 58 will engage the plate I6 and move the same rearwardly, opposite to the direction indicated by the arrow 82. This movement of said plate will rock the link mechanisms 64 on the two side leg plates II and I2 into the positions indicated by dotted lines in Fig. 3, and the forward catch or dog end 88 of the linger or bar '88 will engage the iirst Atooth or slot 62 in the plate 51 and will move said plate with'the compartments thereon in a forward direction until the rst row 14 of the containers 60 has been forwardly removed from my Y in an upward direction, the second row 14a of the container 6I will be filled, as has been described hereinbefore with reference to the ilrst row 14 thereof. Corresponding to the apertures 21 and the recesses 84 in the respective plates I0 and I6, apertures 81 are provided in the cover plate I5 to the rear of said apertures 21 (Figs. 1 and 6).

A cylindrical backwardly inclined lling guide 88 may be provided over every opening or hole 81 containing a stack of sealing disks 83, and it will be obvious that upon the forward movement of the plate I6, each recess 84 will carry the lowermost sealing disk 83 from its stack, while upon the rearward movement of said plate I'B, itsv recesses 84 will again be filled withv the next lowermost disks in the stacks 84.

It also will Vbe seen that upon the forward movement of said plate I8, that is preparatory to the sealing operation and the position of the parts shown in Fig. 3, the link mechanism 84 will be operated in a reverse direction to the one described hereinbefore, and placed into its position shown by the full lines in Fig. 3, the catch or dog 86 riding rearwardly, leaving the first notch or tooth 82 and riding idly until it will arrive and snap into the next notch 62, in this manner being ready to again propel the plate 51 with the pitchers 6I thereon with another row when the handle 41 is again moved upwardly preparatory to the filling operation, and the teeth 50 will again move the plate I8 in a rearward direction.

I may, finally, also provide /a yieldable resilient locking device 88a at each side of my device, their outwardly bent portions 88 being adapted to snap into a. respective slot 83 in the edge of the plate 51 and thereby secure an aligned position for the respective row of pictures 6I with the row of the filling funnels 22, while on the forward movement of said plate 51 under the action of the arm or -finger 68said resilient locks will yield, moving outwardly from the slots 63 and permitting such a movement ofthe plate51 with the containers 5 6I thereon.
